Custom Sub Box For Alpine Type R 12 99 Chevy Extended Cab Seal Subwoofer To Box?

Seal subwoofer to box? - custom sub box for alpine type r 12 99 chevy extended cab

I'm building a custom box for my Alpine Type R 12 "and I am a little confused. I know I have to seal all the joints and the stone of the terminal in the box with silicone, but I'm not sure if the so - Woofer should seal to the front and it is necessary is to seal the woofer with bolting, or okay? "What happens if I need, is the work of silicon or link to the sub - committee in the box?
